Spray foam blocking return chases and supply runs
Why it happens here
Homeowners in Riverbend often hire insulation contractors who spray foam into any open cavity, including duct chases. It seals air leaks, but it also blocks the duct. This is the single most common problem we see in 02038.
Our approach
We camera-inspect the chase first, then remove the foam in sections without damaging the duct. After cleaning, we reseal the chase properly with mastic and foil tape so it stays airtight without blocking airflow.
